2016-10-21[media] videodev2.h Add HSV formatsRicardo Ribalda Delgado1-0/+4
These formats store the color information of the image in a geometrical representation. The colors are mapped into a cylinder, where the angle is the HUE, the height is the VALUE and the distance to the center is the SATURATION. This is a very useful format for image segmentation algorithms.

2016-08-23[media] v4l2-core: Add support for touch devicesNick Dyer1-0/+9
Some touch controllers send out touch data in a similar way to a greyscale frame grabber. Add new device type VFL_TYPE_TOUCH: - This uses a new device prefix v4l-touch for these devices, to stop generic capture software from treating them as webcams. Otherwise, touch is treated similarly to video capture. - Add V4L2_INPUT_TYPE_TOUCH - Add MEDIA_INTF_T_V4L_TOUCH - Add V4L2_CAP_TOUCH to indicate device is a touch device Add formats: - V4L2_TCH_FMT_DELTA_TD16 for signed 16-bit touch deltas - V4L2_TCH_FMT_DELTA_TD08 for signed 16-bit touch deltas - V4L2_TCH_FMT_TU16 for unsigned 16-bit touch data - V4L2_TCH_FMT_TU08 for unsigned 8-bit touch data This support will be used by: - Atmel maXTouch (atmel_mxt_ts) - Synaptics RMI4. - sur40 Signed-off-by: Nick Dyer <[email protected]> Tested-by: Chris Healy <[email protected]> Signed-off-by: Hans Verkuil <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]> Acked-by: Dmitry Torokhov <[email protected]>

Most of what is marked as 'experimental' has been around for years. Time to drop that annotation.

2015-06-05[media] videodev2.h: add support for transfer functionsHans Verkuil1-1/+40
In the past the transfer function was implied by the colorspace. However, it is an independent entity in its own right. Add support for explicitly choosing the transfer function. This change will allow us to represent linear RGB (as is used by openGL), and it will make it easier to work with decoded video material since most codecs store the transfer function as a separate property as well.

2015-05-30[media] videodev2.h: add macros to map colorspace defaultsHans Verkuil1-0/+30
The mapping of COLORSPACE_DEFAULT, YCBCR_ENC_DEFAULT or QUANTIZATION_DEFAULT to proper non-default values is fairly complex, and it is something that needs to be done both in the kernel and in userspace. So add macros that can do this conversion, making this available to both kernel and userspace. Signed-off-by: Hans Verkuil <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>

2015-05-30[media] videodev2.h: add COLORSPACE_DEFAULTHans Verkuil1-0/+6
V4L2_COLORSPACE_DEFAULT is added so we have a specific define for the default case where applications do not set it but leave it to 0.

2015-04-08[media] videodev2.h/v4l2-dv-timings.h: add V4L2_DV_FL_IS_CE_VIDEO flagHans Verkuil1-0/+6
In the past the V4L2_DV_BT_STD_CEA861 standard bit was used to determine whether the format is a CE (Consumer Electronics) format or not. However, the 640x480p59.94 format is part of the CEA-861 standard, but it is *not* a CE video format. Add a new flag to make this explicit. This information is needed in order to determine the default R'G'B' encoding for the format: for CE video this is limited range (16-235) instead of full range (0-255). The header with all the timings has been updated with this new flag.

2015-04-02[media] v4l2_plane_pix_format: use __u32 bytesperline instead of __u16Hans Verkuil1-2/+2
While running v4l2-compliance tests on vivid I suddenly got errors due to a call to vmalloc_user with size 0 from vb2. Digging deeper into the cause I discovered that this was due to the fact that struct v4l2_plane_pix_format defines bytesperline as a __u16 instead of a __u32. The test I was running selected a format of 4 * 4096 by 4 * 2048 with a 32 bit pixelformat. So bytesperline was 4 * 4 * 4096 = 65536, which becomes 0 in a __u16. And bytesperline * height is suddenly 0 as well. While the vivid driver may be a virtual driver, it is to be expected that this limit will be hit for real hardware as well in the near future: 8k deep-color video will already reach it. The solution is to change the type to __u32. The only drivers besides vivid that use the multiplanar API are little-endian ARM and SH platforms (exynos, ti-vpe, vsp1), so this is safe.

2014-07-17[media] v4l: Support extending the v4l2_pix_format structureLaurent Pinchart1-1/+14
The v4l2_pix_format structure has no reserved field. It is embedded in the v4l2_framebuffer structure which has no reserved fields either, and in the v4l2_format structure which has reserved fields that were not previously required to be zeroed out by applications. To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer structure, and use the priv field as a magic value to indicate that the application has set all v4l2_pix_format extended fields and zeroed all reserved fields following the v4l2_pix_format field in the v4l2_format structure. The availability of this API extension is reported to userspace through the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the priv field is still set to the magic value at [GS]_FMT return wouldn't be enough, as older kernels don't zero the priv field on return. To simplify the internal API towards drivers zero the extended fields and set the priv field to the magic value for applications not aware of the extensions.
